PAPER-ROLL.

To all Wilma it may concern:

Be it known that I, SETH WHEELER, a citizen of the United States of America, and a resident of Castleton, county of Renssclaer, and State of New York, have invented certain new and useful Improvements in Paper-Rolls, of which the following 18 a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to paper rolls such. as those of paper towels, toilet paper or otherkinds of paper or other fabric which are adapted to be rotatably supported by a fixture. Its object is to provide a roll having a core or other element or elements with which a part or parts of the holding fixture may engage and more particularly to a roll especially designed for use with such a fixture as that disclosed in a copending appliation for patent, Serial No. 781,660 filed by me herewith.

I will describe my invention in the fol lowing specification, and then point out the novel features thereof in appended claims.

In the drawings: Figure 1 is an elevation partly in section of a roll of paper embodying my invention. 'F1gs. 2 and 3 are respectively a front elevation and an end view of a modified form of the core of my improved roll. In Figs. 4: and 5 another modification of the core is shown in front elevation and end view respectively. A still further modification of the core is shown in Fig. 6 which is a sectional elevation of one end of the core. Fig. 7 shows in bottom plan view partly in section, a roll like that shown in Fig. 1 in position upon its holding fixture. In Fig. 8 the parts shown in Fig. 7 are shown in end elevation. Flg. 9 is an end elevation of one of the engaging members which form part of the fixture. Fig. 10 is a view corresponding to Fig. 9 of a modified, engaging member adapted for use with a roll having a nonfiexible core and Fig. 11 is a sectional View of the same.

Like characters of reference designate corresponding parts in all the figures.

30 designates a tubular cylindrical core of cardboard or other desired material which may be capable of some distortion, upon which is wound paper 31. Near the ends of the tube it is pressed inward to form an nular shoulders 32 which form inwardly Specification of Letters Patent.

Serial No. 731,661.

lfacing surfaces which are arranged to be engaged by portions of the fixture. In 'order to show the way in which this roll used I will briefly describe the fixture .{which is more fully and specifically described and is claimed in the aforesaid application for patent Serial No. 731,660 The fixture comprises a base 10 from the opposite ends of which project arms 11 and 13. Each of these arms rotatably supports an engaging member 20, the two being in Iaxial alinement with each other. The arms may be and the engaging members are adjustable toward and from each other. The engaging members may be triangular in iform as shown in Fig. 9 with their corners rounded ofi conically. The largest radii of these rounded corners is the same as the internal radius of the core 30. When the paper roll constructed asdescribed is to be placed in such a fixture, the engaging me1nbers are moved apart far enough to clear the roll and are then thrust into the ends of the core until they pass the shoulders 32. This may be done because the na ture of the core and its collars is such as to permit of sufficient distortion to allow the curved ends of the engaging members to enter, and the elasticity of the core will then cause it to resume its original cylindrical shape, so that the corners of the en gaging members will then lie against the inside of the core and back of the shoulders formed in the tube. Now the arms of the fixture are moved up against the ends of the roll and the engaging members moved away from each other. The latter is accomplished by turning a thumb-nut 25 on a threaded shank 23 on which one of the engaging members is supported. This puts a tensional strain upon the roll and draws the arms up against the ends of the roll with more or less pressure. Thus an ad justable frictional engagement between the fixture and the roll is obtained by means of which the desired tension on the paper may be maintained as it is drawn off from the roll.

A tubular core 30 is shown in Figs. 2 and 3 in which is out near its ends a plurality of holes 33 corresponding in position to the cornets of the holding members. The latter may be forced into a core of this kind until its corners slip into the holes 33 and then when drawn apart they will engage the outiidle1 edges of these holes to get the desired The core 3O shown in Figs. & and 5 is much like the core 30*, but in this case none of the material of the core is removed,it is only cut as shown at 34 so that when the engaging members are forced into place the out parts of the core will be forced into the paper thereby. Otherwise it is used in the same way the core 30 is used.

In Fig. 6 a tubular core 3O is shown inside of which are fastened collars 35 which form the desired shoulders. Only one end of this core is shown but it is to be understood that its other end may be similarly constructed.

lVith other forms of fixtures it is not necessary to have the core flexible as it is well within the present invention to provide a roll which may be used with a fixture which has an engaging member capable of itself contracting upon being forced through the restricted end of the core. A member of this character is shown in Figs. 10 and 11 and comprises a solid body &0 similar in shape to the end member 20 of Fig. 9 having a plurality of spring clips l1 secured to it and so arranged as to enter readily into the restricted end of a non-flexible core and to then expand to prevent the withdrawal of the member.

It is to be noted that a roll constructed as above described cannot be removed from the fixture after it has been placed therein until it is unwound and its core broken. Thus it cannot be stolen or misplaced.

One of the objects of this invention is to provide a roll hitherto unobtainable, which is especially designed for a specific type of supporting fixture on which fixture other forms of rolls cannot be used.

What I claim as a new article of manufacture is:

l. A tubular core adapted to be rotatably supported in a stationary fixture, said core comprising shoulders capable of resisting opposed pressures outward, said shoulders having inwardly-facing surfaces and being connected with the core near the ends thereof and adapted to be engaged by the fixture.

2. A tubular core adapted to be rotatably supported in a stationary fixture, said core having inwardlyfacing surfaces near its ends capable of resisting pressures outward and adapted to be engaged by the fixture.

3. A tubular core of cardboard for a cylindrical paper roll having fixed annular shoulders impressed therein forming surfaces capable of resisting pressures outward permitting the insertion of a portion of a supporting fixture but preventing the re moval of such portion of a fixture.

l. A tubular core of cardboard for a cylindrical paper roll having annular shoulders impressed therein capable of resisting opposed pressures outward, said core being capable of distortion to permit the insertion of a portion of a supporting fixture but preventing the removal of such portion of a ture.

In testimony whereof I have hereunto set my hand this 14th day of November, 1912, in the presence of two witnesses.
